Macintosh game publisher Aspyr Media has updated their website to officially announce their newest product, Stars Wars Galactic Battlegrounds: Clone Campaigns, an expansion pack for the real-time strategy game. While the add-on was revealed as coming to the Mac back at Macworld New York, this is the first information to be posted on the company's web site. Along with the expected new units and structures, Clone Campaigns will also feature new upgrades and powerups, a larger force at your disposal (up to 250 units per player), the ability to replay old campaigns with new features and units, added goodies to the scenario editor, and more. Here is a list of included features:

Clone Campaigns, is currently in the Beta stage, and is slated to be released in late September or Early October. A related news item at Westlake Interactive notes that the "programming on Clone Campains has progressed extremely well and we expect the software to hit Final Candiate in the near future."
